Abstract
A method for blow molding bottles having a hole formed in a molded interior recess extending from a top face of a bottle neck includes the steps of: (i) providing a mold having a neck forming cavity with an end flange surface therein; (ii) disposing a parison of molten material within the mold; (iii) introducing pressurized fluid into the parison to expand it against the mold walls, thereby forming a final shape of the bottle; (iv) forming the interior recess in the bottle by advancing a recess forming rod through a hole in the end flange surface and into the neck forming cavity; and (v) creating a dispensing hole in the interior recess by advancing a punch through a hole in an end face of the recess forming rod.
